The airFiber AF5/AF5U, referred to as the AF5 in this Design Guide, features unique functionality that requires you to be cognizant of the installation environment. For best performance, you must install the AF5 as high up as possible, with a line of sight free from obstructions. This is especially true in FDD (Frequency Division Duplexing) mode, as there is a requirement to maximize channel/spectrum reuse.
Any objects in front of or near the front of the AF5 can have a significant impact on overall performance. The AF5 should be installed 1 m (3.3 ft) below the highest point of the structure to reduce the risk of a lightning strike. When the AF5 must be installed above a metallic surface like a corrugated flat roof or water tower, then you should ensure that the AF5 is located more than 3 m (10 feet) above the metal/reflective surface.
